Geometry

Question Analysis:
This is a translation with coordinates multi-select question.
Main focus: Applying a translation rule to each vertex correctly.

Key Concept Explanation:
Apply the rule (x − 1, y + 4) to each vertex.

Step-by-Step Solution:
A(2, 3) → A′ = (2 − 1, 3 + 4) = (1, 7) ✅
B(4, 3) → B′ = (4 − 1, 3 + 4) = (3, 7) ✅
C(2, 6) → C′ = (2 − 1, 6 + 4) = (1, 10) ✅
So:
A′ = (1, 7) → A ✅
B′ = (3, 7) → B ✅
C′ = (1, 10) → D ✅
C′ = (3, 10) ❌
A′ = (3, 7) ❌ (That's B′)
